If you consider using ConTeXt for a paper with a proper formula numbering please wait until it is implemented in mkiv. At the moment only a very limited formula numbering is possilbe:
* number formula(s) with a plain number
* number formula(s) with a subnumber
Not possible is at the moment:
* Table of formulas
* Named subformulas
* Mixure of formulas and subformulas in one block
* Reference on a (sub-)formula without having it listed in the Table of formulas
For more details and actual state see mailing list and [http://wiki.contextgarden.net/User_talk:Zenlima Summary of formula numbering problem].

Hi, I use this page to support my question regarding context and summarize the result. Once a problem is solved I will move that text into the "normal" wiki pages.
=Duplex with marginsBug: Layoutchange inside page while duplexmode=
Problem: At A both sided document in which the moment mkiv creates wired margin on every duplex layout has to switch inside a page. It appears when lines seperates works fine with text only content, but as soon "bigger" objects (like a table) are involved the marginstextarea get messedup (shifted horizontally).
\definelayout[WithMarginnotes] [grid=no,topspace=3cm,height=24cm,backspace=3cm,cutspace=0cm,leftmargin=1cm,leftmargindistance=0In the following example inner and outer margin notes are added to make it more obvious.4cm,width=12.1cm,rightmargindistance=0.4cm,rightmargin=3.5cm] <texcode> \setuplayoutsetuppapersize[WithMarginnotesA4] \setuppagenumbering[alternative=doublesided,location=A4] \showframe

=Bug: Formula numbering - subnumbers and list of formulas=
 
All following example have following frame:
 
<texcode>
\usemodule[newmath]
 
\setupformulas[way=bytext,prefix=no]
\setupsubformulas[conversion=romannumerals]
 
\starttext
...(example placed here)...
\stoptext
</texcode>
 
 
==What works==
 
===formula===
 
Expected formular number: (1)
 
<texcode>
\placenamedformula[one]{Der einfache Test}
\startformula
c^2 = a^2 + b^2.
\stopformula
</texcode>
 
Result: (1) -> '''Works'''
 
===align - formular [+]===
 
Expected formular numbers: (1) and (2)
 
<texcode>
\placeformula
\startformula
\startalign[n=3, align={right,middle,left}]
\NC PM \xrightarrow \NC R_{PM} \NC \xrightarrow PM \NR[+]
\NC R_{PM} \NC = \NC \{ A, B, C, D, E\} \NR[+]
\stopalign
\stopformula
</texcode>
 
Result: (1) and (2) -> '''Works'''
 
 
===align - subformular [+]===
 
Expected numbers: (1.a), (1.b), (1.c), (1.d) and reference on (1) and (1.b)
<texcode>
\startsubformulas[eq:ax=b]
\placeformula
\startformula \startalign
\NC a \NC \eq b \NR[+]
\NC c \NC \neq d \NR
\NC \NC \neq f \NR[eq:sub]
\NC \NC \geq g \NR[+]
\NC \NC \leq h \NR[+]
\NC \NC \eq i \NR
\stopalign \stopformula
\stopsubformulas
</texcode>
 
Result: (1.a), (1.b), (1.c), (1.d) -> '''Works'''.
 
BUT: Every formula with a reference is automatic listed in the table of formulas (nameless) - at the moment there is no possiblity to have a reference without listing the formula.
 
===eqalignno - formula===
 
Taken from wiki and removed the subformulanumber. Expected formular numbers: (1), (2), (3) and (4):
 
<texcode>
\placeformula
\startformula
\eqalignno{
c^2 &= a^2 + b^2 &\formulanumber \cr
c &= \left(a^2 + b^2\right)^{\vfrac{1}{2}} &\formulanumber\cr
a^2 + b^2 &= c^2 &\formulanumber \cr
d^2 &= e^2 &\formulanumber \cr}
\stopformula
</texcode>
Result: (Picture of pdf1), (2), (3) and (4) -> '''Works'''
Once the empty lines are removes
==What does not work==  ===List of formulas=== <texcode>\placelist[formula][criterium=all,alternative=c]</texcode> The list of formulas seems to be totally out of order.

the result is ok:Expected formular numbers (1), (1a), (1.c) and (2); reference on (2); list entries (1.c) -> "Yea!" and (2) -> "Ups"
<texcode>\placeformula\startformula\eqalignno{ c^2 &= a^2 + b^2 &\formulanumber \cr c &= \left(a^2 + b^2\right)^{\vfrac{1}{2}} &\formulanumber[sublevel={a}]\cr a^2 + b^2 &= c^2 &\formulanumber[File:duplex-margin-without-empty-linessublevel={.pngc},listlabel={Yea!}]\cr d^2 &= e^2 &\formulanumber[listlabel={Ups},reference={eq:ups}]\cr}\stopformula</texcode>
But this is only a theoretical construction. In real life texting you have often empty lines.
==[stacking=continue] does not solve the problemSummary===
All three commands:* \NR* \placeformula* \formualanumber will share the same attributes:* sublevel (Quelltextmaybe better: formulalevel or just level?)<br />to define and concrete the (sub-)level of the formula* listlabel (maybe textlabel? the numberlabel is still needed)<br /> to add a entry in the list of formulas* reference<br />just a classic reference in order to link to itso that the syntax is more intuitive during writing.
(Picture of pdf)Also. this way the commands:* placesubformula* placenamedformula* placenamedsubformula* startstopsubformulas* subformulanumberwill become needless.
